Just to say thank you for your advice, bought and collected Screw Tite screws from Screwfix and my one panel replaced in 10 minutes. I am going to buy different sizes of the same product. They are excellent, no pre drilling and my OXO cordless buried them with no effort. I chose the 70mm length. So cheers mate!
